- is a period of approximately 223 synodic months
- start in the same postion
- 1/3 day, Earth rotates an additional ≈ 360°/3 = 120° and consequently eclipses do not reoccur at the same longitudes compared to the last cycle.
- However, after three cycles, Earth rotates an additional ≈ 360° and consequently eclipses do reoccur at approximately the same longitudes (and latitudes) compared to three cycles ago.
- 1/3 day, Earth rotates an additional ≈ 360°/3 = 120° and consequently eclipses do not reoccur at the same longitudes compared to the last cycle.
- 6585 1 3 days.
- earth spins 130 degrees in one day
- start in the same postion
- EQUATIONS
- approximately 6585.3211 days, or 18 years, 11 days, 8 hours
- The earliest discovered historical record of what is known as the saros is by Chaldean (neo-Babylonian) astronomers in the last several centuries BC
